Hi there By 'good' I assume you mean 'better'? Because all carseats are safe. We don't know which are the 'good' ones because no one releases their test results.

Now, if by 'good' you actually mean plush or comfy....then I get it. Sceneras and Maestros are really great seats, but if given the option, I'd want my Frontier85 and Roundabout55. But I am a snob like that.

by "good" I mean that ones that are already sitting in my car and don't cost me more money and my kids are comfortable with...

I don't know anything about the other seats, but I'm not going to buy them new ones ... that totally came out wrong, I really apologize
